## Overview

The RomoTech 82123879 is a durable, 8-gallon polyethylene water tank made in the USA, designed for reliable outdoor use. Featuring UV-stabilized, rustproof material, clear level markings, and an oversized lid with a 3/4" NPT outlet, it offers easy filling, draining, and secure transport. Ideal for potable water and non-flammable liquids, this tank excels in mobile, agricultural, and industrial applications.

## Description

In Indiana, a charge of medium‑density polyethylene enters a rotational mold and emerges as a precise 8 gallon water tank—a horizontal domed reservoir designed for everyday reliability. The natural, translucent wall lets operators verify fluid level instantly, while molded gallon and liter markings provide an exact read. Outdoors, UV‑stabilized poly resists fading and warping; in service, it won’t rust or corrode. A 5‑1/2" lid (5" opening) and easy‑tighten cap simplify refills, and a built‑in bulkhead fitting with a 3/4" NPT outlet makes fast work of draining, siphoning, or hose connection. Molded tie‑down channels accept saddle straps so this portable water tank rides securely as a truck bed water tank or trailer water tank, ready for farm chores, job sites, and water tank for car detailing setups. Rated for non‑flammable liquids to 140°F, it serves confidently as a potable water tank, a rugged water storage tank, or an RV water tank for extended trips. Made in the USA, it’s engineered for cleanability, durability, and dependable performance wherever you need compact capacity and square‑profile stability.
